Methods and compositions for reducing the environmental impact of animal waste
View Patent ↗Methods for reducing the environmental impact of animal waste are described. In particular embodiments, the methods comprise administering to an animal an enzyme, such as alkaline phosphatase, that is effective to reduce the amount of a detrimental compound, such as ammonia or phosphorous, that is present in or released from animal waste. Also provided is a method for increasing phosphorus digestion in an animal. Compositions suitable for use in such methods are also described.
1. A method for increasing phosphorus digestion in an animal, comprising administering to said animal an effective amount of a composition comprising an isolated and purified alkaline phosphatase;
wherein said alkaline phosphatase is SEQ ID NO: 1, or an alkaline phosphatase comprising amino acids 33 to 572 of SEQ ID NO: 1;
wherein said alkaline phosphatase comprises serine at position 102; and
wherein said composition is administered orally.
2. The method of claim 1 , wherein said animal is a young animal.
3. The composition of claim 2 , wherein said animal is a chicken or turkey.
4. The composition of claim 2 , wherein said animal is a swine.
5. The method of claim 2 , wherein the alkaline phosphatase is administered during one or more of the starter phase, the grower phase, and/or the finisher phase.
6. The method of claim 1 , wherein said alkaline phosphatase is formulated in animal feed.
7. The method of claim 1 , wherein said alkaline phosphatase is formulated in an animal feed additive.
8. The method of claim 1 , wherein one or more additional active ingredients are administered to said animal.
9. A method for increasing the growth rate of an animal, comprising administering to said animal an effective amount of a composition comprising an isolated and purified alkaline phosphatase;
wherein said alkaline phosphatase is SEQ ID NO: 1, or an alkaline phosphatase comprising amino acids 33 to 572 of SEQ ID NO: 1;
wherein said alkaline phosphatase comprises serine at position 102; and
wherein said composition is administered orally.
10. The method of claim 9 , wherein said animal is a young animal.
11. The composition of claim 10 wherein said animal is a chicken or turkey.
12. The composition of claim 10 , wherein said animal is a swine.
13. The method of claim 10 , wherein the alkaline phosphatase is administered during one or more of the starter phase, the grower phase, and/or the finisher phase.
14. The method of claim 9 , wherein said alkaline phosphatase is formulated in animal feed.
15. The method of claim 9 , wherein said alkaline phosphatase is formulated in an animal feed additive.
16. The method of claim 9 , wherein one or more additional active ingredients are administered to said animal.
